Delivery Condition
TermSymbolExplanation
Cold-finished/hard
(cold-finished as-drawn)
BK		No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft
(lightly cold-worked)
BKW		After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
AnnealedGBKAfter the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
NormalizedNBKThe tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
